LiteSpeed max connections per client

Does the Litespeed have any setting for maximum connections per client?

I have the problem regarding a Litespeed Web Server Enterprise v3.3.15 which seems to allow only two connections from the same client per time.

It is running a rails backend which is allowed to open 5 connections. The server connection limit is set to 2000 connections. If I load the data from the same browser cached in a squid cache there are four connections at the same time. If the connections are send directly to the server there are only two connections at the same time.
